32 GB DDR5-4800 ECC Registered DIMM

This 32 GB module runs at 4800 MHz with CL40 latency and 1.10 V. It uses a 288-pin DDR5 interface, registered signal buffering and on-die ECC for data integrity. The dual-rank 2Rx8 organisation suits multi-channel server platforms that require registered memory.

Verify registered DDR5 support and slot count

Confirm the motherboard accepts registered DDR5 DIMMs and provides enough 288-pin slots for the desired capacity. The memory controller must operate at 1.10 V and support CL40 timing at 4800 MT/s. Unbuffered or non-ECC boards will not work with this module.

Replaces slower or non-ECC DDR5 modules

Upgrading from lower-speed DDR5 or unbuffered ECC memory adds registered buffering and 4800 MT/s throughput for heavier virtualization or database workloads. The jump is worthwhile when the platform supports registered DIMMs and the workload benefits from higher bandwidth and error correction.

Questions about this item

Does the 32GB DDR5 module ship with any cables or heat spreader, or must those be bought separately?

The module arrives as a single 288-pin DIMM without a heat spreader; no cables or extra accessories are included.

Should I choose the CL40 4800 MHz registered ECC version or a different speed or latency for my server?

This part is a 32GB 2Rx8 registered ECC DIMM at 4800 MHz CL40; select it when your platform requires registered ECC DDR5 at that speed and latency.

What does the 4800 MHz rating mean once the DIMM is installed in a server?

The memory runs at 4800 MT/s with CL40 timing at 1.10 V, delivering the bandwidth and error correction your registered DDR5 platform expects.
